In this paper, the effect of using different configurations absorber plate, including one line finned flat and two lines on thermal performance a plate – double passing solar air heater was investigated experimentally. L- shape fins are soldered to roughen generate vortices enhance heat transfer between working fluid (air) improve efficiency. The outdoor experimental test carried out during Feb...

A review of studies focused on promoting the rate heat transfer with help an optimum rise in friction factor, by offering a simulated irregularity to interior surface absorber plate SAH, is expressed. In this article effort has been made explore different coarseness configurations as used number researchers boost SAH rate. Furthermore, correlations developed for Nusselt and factor are also pres...

In order to obtain the best performance of the solar air heaters, it is necessary to find optimum performance conditions. The aim of this research paper is to achieve optimum conditions, by comparing single and double pass solar air heaters. Also, a brief review study of various related research works of all scenarios for a single and double pass and packed bed (including particle technologies)...
